*Notice: COM header can function as RS232/422/485 port header. In normal settings COMfunctions
as RS232 header. With compatible COM cable COM can function as RS422 or RS 485 header. User
also needs to go to BIOS to set ‘Transmission Mode Select’ (refer to Page-33) at first, before using
specialized cable to connect different pins of this port.
